Modeling and Analysis of Complex Systems

by Gautam Biswas and Eric-Jan Manders last modified 2007-05-07 15:54


The Modeling and Analysis of Complex Systems (MACS) group at Vanderbilt University conducts research to study the behavior of embedded and hybrid physical systems. These systems are characterized by mixed discrete/continuous behaviors that are effectively described using the theory of hybrid systems. From new theoretical results we construct tools to support modeling and analysis of hybrid systems in the context of embedded system realizations. Specifically, we develop capabilities for

  • Modeling and analysis of complex systems
  • Advanced model-based fault detection and isolation (FDI) and diagnosis
  • Fault adaptivity
  • Simulation-based prognosis systems
  • Integrated systems health management (ISHM) of high availability and mission critical engineering applications.

The MACS group is based in the Department of Electrical Engineering and Computer Science of the School of Engineering. It is affiliated with the Institute for Software Integrated Systems (ISIS). Resources available to the group includes a three tank system process control testbed that is located in Room 314, Featheringill Hall.

The research summary gives an overview of our research objectives and core strengths. We apply our work in a number of projects, both in a laboratory setting, and in collaboration with government and industry sponsors on real-world problems. Current principal sponsored research applications include the development of hierarchical  diagnosis and prognosis schemes for civil engineering structures, aircraft and spacecraft power generation and power distribution systems, and Fault Adaptive Control Technology (FACT) for aerospace applications.

In the past, we have worked on projects that include the development of Advanced Life Support System (ALS) technology for human space exploration, fuel transfer systems for aircraft, the secondary sodium cooling loop for nuclear reactors, and the cooling system for automobile engines.
